is chop blocking legal?

Below Waist
ARTICLE 2. a. A block below the waist is a block in which the force of the initial
contact is below the waist of an opponent who has one or both feet on the ground.
When in question, the contact is below the waist (Rule 9-1-6).
b. A blocker who makes contact above the waist and then slides below the waist has
not blocked below the waist. If the blocker first contacts the opposing player’s
hands at the waist or above, it is a legal “above the waist’’ block (Rule 9-1-6).

Chop Block
ARTICLE 3. A chop block is a high-low or low-high combination block by any two
players against an opponent (not the ball carrier) anywhere on the field, with or without
a delay between blocks; the “low” component is at the opponent’s thigh or below.
(A.R. 9-1-10-I-IV). It is not a foul if the blockers’ opponent initiates the contact. (A.R.
9-1-10-V)

Blocking Zone
ARTICLE 6. a. The blocking zone is a rectangle centered on the middle lineman of the
offensive formation and extending five yards laterally and three yards longitudinally in
each direction. (See Appendix D.)
b. The blocking zone disintegrates when the ball leaves the zone.
Low-Blocking Zone
ARTICLE 7. a. The low-blocking zone is the rectangle that extends seven yards
laterally in each direction from the snapper, five yards beyond the neutral zone and
back to Team A’s end line. (See Appendix D.)
b. The low-blocking zone disintegrates when the ball leaves the zone.

Blocking Below the Waist
ARTICLE 6. a. Team A prior to a change of team possession: Consider a low-blocking
zone seven yards on each side of the snapper extending five yards beyond the neutral
zone and back to Team A’s end line (Rule 2-3-7 and Appendix D).
1. The following Team A players may legally block below the waist inside this
zone until the ball has left the zone: (a) players on the line of scrimmage
completely within this zone and (b) stationary backs who are at least partially
inside the tackle box and at least partially inside the frame of the body of the
second lineman from the snapper. (A.R. 9-1-6-V)
2. Players not covered in paragraph 1 (above) while the ball is still in the zone,
and all players after the ball has left the zone, are allowed to block below the
waist only if the force of the initial contact is from the front, but they may not
block below the waist if the force of the initial contact is from the side or back.
“From the front” is understood to mean within the clock-face region between
“10 o’clock and 2 o’clock” forward of the player being blocked. (A.R. 9-1-6-
I-II, IV, VII-VIII)
3. Once the ball has left the zone a player may not block below the waist toward
his own end line. (A.R. 9-1-6-III)
4. Players not covered in paragraph 1 (above) may not block below the waist
toward the original position of the ball at the snap.
b. Team B prior to a change of team possession:
1. Other than in paragraphs 2 and 3 (below), players of Team B may block below
the waist only within the area defined by lines parallel to the goal line five
yards beyond and behind the neutral zone extended to the sidelines. Blocking
below the waist by players of Team B outside this zone is illegal except against
the ball carrier. (A.R. 9-1-6-VI, IX)
2. Players of Team B may not block below the waist against an opponent who is in
position to receive a backward pass.
3. Players of Team B may not block below the waist against an eligible Team A
pass receiver beyond the neutral zone unless attempting to get to the ball or ball
carrier. This prohibition ends when a legal forward pass is no longer possible
by rule.

yes, but we'll see a lot of legal cut blocks.***

He askeded two questions.

not sure i tried, the whole thing was convoluted so keeping

Re: He askeded two questions.

Yes as long as the DL is not engaged by another player.

A "chop block" is illegal, but a cut block is legal.

Re: A "chop block" is illegal, but a cut block is legal.

Also, the offensive player cannot be "in motion"...
